This is a Lithium Ion and Lithium Polymer battery charger based on the MCP73833. It uses a USB mini-B for connection to any computer or 'USB wall adapter'. Charging is performed in three stages: first a preconditioning charge, then a constant-current fast charge and finally a constant-voltage trickle charge to keep the battery topped-up. The fast-charge current is 500mA by default, but is easily adjustable from 100mA up to 1000mA by soldering a through-hole resistor on-board.

This board is great for DIY projects because it has 3 indicator LEDs - one for power, one for charging status and a third that indicates when charging is complete. Keep the battery connected to the charger and pass power through the additional JST connector using the included cable!

For use with Adafruit's Lipoly batteries only! Other batteries may have different voltage, chemistry, polarity or pinout.

500mA charge current, adjustable from 100mA to 1000mA by soldering in a resistor

Separate JST connectors for battery and load system so batteries don't have to be removed for charging

Chip supports a 10K NTC thermistor which Adafruit have stuffed as a plain 10K. For people who require temperature monitors (using high charge rates), remove the 10K and solder in the thermistor in its place

Nice product. Would be great if there was datasheets attached for the breakout of the IC. Examples on wiring up the LED's would also be helpful. Awesome product tho, thanks. (Posted on 13/09/2016)
